MACHINERY FOR WORMING RIGGING.

Specification of Letters Patent No.

To all wit-0m, itmag concern.

Be it known that I, JONATHAN O. GINN, of South Tho-maston, in the countyof Lincoln and State of Maine, have invented a new and useful Machinefor Worming Rigging; and I do hereby declare that the same is fullydescribed and represented in the following specification and the accompanying drawings, letters, figures, and references thereof.

Of the said drawings, Figure 1, denotes a side elevation of my saidinvention. Fig. 2, is an end view of it. Fig. 3, is a longitudinal andcentral section of it.

On each of the four sides of a box or frame A, there is arranged a reelor bobbin, B, which is so supported by arms O, C, pro jecting from thebox as to be capable of freely revolving on its axis. The said box A, ismade with a bore or passage, D, extending through it, such passage beingprovided at one end with what I term the traveler, which consists of aseries of helical threads that are the counterparts of the spacesbetween the strands of a rope. If we suppose a rope to represent a fourthreaded male screw, the traveler would be a four threaded female screwmade to correspond with and turn on it. From the traveler to the rearend of the box, the passage through the box is made a cylindrical bore,equal in diameter to the external diameter of the rope to be wormed.From each of the reels, when they are provided with the worming, astrand is run through a guide staple, a, there being such a staple toeach reel. From thence the strand is carried to and under a frictionband or spring, 6, and is passed through one of four inclined passagesor holes 0, c, 0, 0, made in the front end of the box, A. The

friction spring, has a screw, cl, passing through it and screwed intothe box, the same being to enable a person to regulate the friction inthe strands, so as to insure an 11,645, dated September 5, 1854.

even draft of them and a close laying of them between the strands of therope.

In order to use my machine, one end of the rope or rigging to be wormedis introduced into the box, A, at the end opposite to that at which thetraveler is placed. The box is next revolved so as to screw up on therope and cause its end to protrude from the box and beyond the traveler.This done, the four strands of the reels are to have their ends laidrespectively between the strands of the rope and fastened to the rope bya seizing or otherwise; if now the box, A, is put in rotation so as toscrew on the rope, the strands or wormings will be gradually drawn fromthe reels and laid between the strands of the rope as fast as the boxprogresses on the rope. This forms a very convenient and portableapparatus to be used on board of a ship or on land for performing theoperation, or what is termed worming rigging.

In Fig. A, I have represented the application of the machine to a rope.In using the machine it may be revolved on the rope by means of a crank,G, ailixed to the box A, or.

the box may be held stationary while the rope is rotated within it, butit is evident that the former mode of operating is the preferable one.

What I claim is- The combination and arrangement of the helicaltraveler, the box or tubular frame and the bobbins or reels, the wholebeing constructed substantially as described and composing a handmachine for the purpose as specified.

In testimony whereof I have hereunto set my signature this fifteenth dayof May A D 1854 JONATHAN O. GINN.
